The Best Mosquito Repellents: Which One’s Right for You?

The Best Mosquito Repellents: Which One’s Right for You?

by James Hubbard, MD, MPH

Last week, we talked about how to prevent mosquito bites. Today, we’ll delve into the vast array of mosquito repellents to help you decide which option is best for you.

All four of the main repellents mentioned in this post work. Some work better on some people than others, so finding the best repellent for you can be just a trial and error thing. But with each one, there are some tips you’ll want to consider.

First, the main tip …

Yes, Mosquitoes Do Prefer Certain People. And You Could Be One.

An insecticide-treated net is rolled up above a bed in Kumi, Uganda. At night, unfurled, it will protect the sleeper from disease-carrying mosquitoes.

I have a good friend who claims he rarely gets bitten by mosquitoes. While others around him are swatting and scratching, he sits in comfort enjoying the great outdoors.

How can that be? And what mosquito-bite prevention techniques can we mere mortals use to keep these bloodsuckers—and sometimes disease carriers—at bay?

The Aedes aegypti mosquito is one of two types that can carry the zika virus.

The Aedes aegypti mosquito is one of two types of mosquito that could spread the Zika virus in the United States.

Zika virus is in the news. It’s an infection you get from certain types of mosquitoes, and it’s linked to a sometimes devastating birth defect called microcephaly. More on that later. Here are the latest facts on the disease and why you should care.

When a Scorpion Sting Turns Deadly

Many scorpion species, including the bark scorpion, glow in the dark if a black light is shined on them.

The bark scorpion likes to live in trees (bark) and hide in woodpiles, under fallen trees, or under your camping bedding.

by James Hubbard, MD, MPH

Scorpions make me think of Westerns. Some cowboy is riding a horse in the desert and they cut to a single scorpion in the sand. It symbolizes that this land is rough, rugged, and dangerous. One sting, and you’re dead.

Cut to real life. While you will find most scorpions in the desert, you may also come across them in many Southeastern and Midwestern states. In all but one species in the U.S., the scorpion sting is similar to a bee sting. Yes, you can be allergic, and the reaction can result in death. (See my bee stings post for signs and treatment of this anaphylactic reaction.)

Usually, though, the scorpion sting just hurts. But there is one scorpion here that causes more problems than others: the bark scorpion. Its sting can affect your brain and nerves. Some people are more vulnerable to a bad outcome than others, but there are things you can do if you see the reaction.

6 Home Remedies for Fire Ant Bites

6 Home Remedies for Fire Ant Bites | The Survival Doctor

If you disturb fire ants, they don’t mess around. They attack. Technically they bite and sting. When they bite, they clamp to your skin with their two strong pincers. Because of this it takes a lot of vigorous brushing to get them off. After biting, they sting by swinging their tail to and fro. One biting fire ant can sting you six to eight times.

by James Hubbard, MD, MPH

Having grown up in the South, I’ve been bitten enough times by fire ants to pretty well know what’s going on before I see them. I know when I feel that distinctive sting (it’s like being touched with a hot match head … for a long time), I’m going to find a lot of creepy, crawling dots.

How to Identify a Spider by Its Bite

How to Identify a Spider Bite, by @James Hubbard

A black widow spider, with its tell-tale red hourglass. If you feel pain when the spider bites, this is likely the culprit.

by James Hubbard, MD, MPH

I’ve seen a lot of spider bites in my day, and more often than not, the spider is never seen. Over the years I’ve developed several tricks for how to identify the spider by the bite.

There are three types of poisonous spiders in the U.S. The brown recluse is found in the southern two-thirds of the country. It likes to hide in boxes so I often wonder if it doesn’t catch an occasional ride by freight. The hobo spider likes it out west. The black widow has been found in every state but Alaska.

Here are my tips on how to identify a spider bite.

4 Ways You Can Get Hantavirus

Deer mice are the most common carriers of hantavirus.

Deer mice are the most common carriers of hantavirus.

by James Hubbard, MD, MPH

Hantavirus has been in the news lately. Several have died from hantavirus pulmonary syndrome, with as many as ten thousand thought to have been exposed while staying in Yosemite National Park this summer. Rats and mice give it to you, so it’s one of those diseases that’s sure to get more prevalent in any long-term disaster.

Hantavirus was officially discovered after a 1993 outbreak in Arizona, New Mexico, Colorado, and Utah. It’s been around much longer but we just didn’t know what caused it.

That year 48 cases were reported. Since then there have been anywhere from 20 to 46 cases per year. Most are in the Western states, but there have been a few in the Midwest and Northeast, with one in Florida. Since the deer mouse is one of hantavirus’s major carriers, and is found all over the place, hantavirus is a risk anywhere.

When the Bugs Aren’t Real

Delusional parasitosis: when the bugs aren't real.

by James Hubbard, M.D., M.P.H.

I never heard of this in medical school, so when I saw my first patient with delusional parasitosis, I was quite bewildered. Here sat a well-dressed, anxious looking guy, scratching all over, who said he scabies and handed me the proof in a tissue. It was a flake of skin.

“And look, Doc. See the bites.” I looked and saw where he’d been scratching—digging and clawing actually—into his skin. But no bugs of any sort.
